Does anybody know what affect on the C/R putting silvertop rods and pistons into a 16v will have (if any).
Im getting a set off HRT and just need to know what head gasket thickness Im gonna use.

I would have thought that the silvertop ones would make less power in a 16v. If you want more copmpression then shave the head and use a trd gasket. maybe get some new pistons off mr revhead if the need be.
BTW too much compression and youll lose power with the stock ecu as youll have to retard the timing.

Yes you can do that, ive done it to a mates car and am going to do it to my car as well. Had to put on an adjustable fuel pressure reg to allow for the raised comp ratio 
To finish first, first you must finish

Thats what I wanted to hear!
The engine may be going F/I in the furure so I'd rather not do anything irreversible the the engine itself, such as shave the head. At least by rebuilding and fitting slightly higher comp pistons and a TRD gasket, its easy enough to swap the pistons to GZE ones and go turbo in the future.

Thats another issue I wanted to clear up.
